> Hello Henrik,Thanks a lot for your reply! I'd just say that I have installed devtools package, when I use find.package("devtools") I get a normal response  - {"[1] "C:/Users/prameet/Documents/R/win-library/3.1/devtools"}. But when I try to load Devtools using library(devtools) function the response I get is -

You are asking the wrong question.  You should be asking why devtools
says that Rtools 3.2 is incompatible.

It's possible I missed something in the setup that devtools is looking
for.  If so, let me know and I'll update Rtools32.exe.
